10V effect on inverter

[RichardK]

I know that if the batteries ( or some them) drops below 10V, something cuts out. I think it is the inverter. I can't remember the solution to get the inverter, or whatever, working again.

The charge relays will isolate a bad battery when if falls below a specific voltage, but I can't remember how low. Your problem seems to be low voltage feeding your inverter. Depending on the inverter, mine will beep a warning that I have low voltage from the battery. In any event you would have to exceed the voltage requirements for things to work properly.

Time to recharge the batteries if thats what your asking.

Depending on the inverter a low voltage will set off and alarm or shut down the inverter do to low voltage. I have a Kisea which at 10.5 volts the inverter will auto shut down. If your batteries get to this level which you do not want to do especially if you have AGM batteries. Your ACR will also go into a lock out. The ACR will lock out at 9.5 V. The other issue with having the battery voltage this low is the battery charger may not sense the batteries with low voltage. Turning a battery charger does not always charge fully discharged batteries. What do you do ? This is when you use the parallel switch or cross over switch ( Battery switch labeled cross over) This is combining the engine battery with the house bank. The engine battery has been isolated from the other batteries and should have a full charge. When the cross over switch is turned on this will take the ACR out of lock out and also allow the battery charger to "see" the 100% discharged house batteries and start to charge them. Do not leave the cross over switch on for the full charge cycle. Leave it on until you start to see the house battery voltage recovering then turn the Cross over switch off. It may take several hours for a 100% discharged house bank to fully charge. Once you feel that the batteries are at full charge maintaining and holding @ 12.7 V I would monitor them for a while to confirm they are not damaged from the full discharge.
